Friend, I am not arguing with you or the fact that a 970 is a capable card or that older cards can still be made to eek out performance on top tier titles. I mentioned the 970 to OP only in terms of price to performance ratio, and in that case it was better to wait for pascal to release terms of value for dollar. As the price WILL come down. The dead tech reference is apt IMEO, because this generation of cards won't be able to preform in terms of their price this time next year. Nvidia pushing the term "TITAN GRADE" is deliberate in order to draw a very clear and distinct line between the pascal generation of cards and their capability from maxwell and I personally feel that a customer should get more value for their dollar than less than 12 months at maximum utility. You may feel otherwise and that is "Ok"
Im not sure why you think 4k is still years away, 4k is here now, on TV's and in OTT video streaming services, currently they are forecasting 8k in the TV market by the end of 2017. it also puzzles me why you think the users of this forum are those who are content with "making do" with less than the top performance of the tech they buy or the ability to maintain that going forward. Toms forum members are by definition the enthusiast market, of which you yourself are a member by your gpu expert status.
When I buy a Graphics card I want to know what its min and max performance will be and what lifecycle I can expect from it at top specs before it begins to underperform. While I don't upgrade every cycle, struggling with dated tech to give me less than ultra settings on the games I play and paying more than I have to for the privilege, is simply not a worthwhile investment of my time or money. Even users who build budget systems still like to be informed about where their purchases fall in the life cycle of the product and what kind of value they can expect to receive. When I am about to drop the better part of 1k on a GPU, it being "good enough" is simply not good enough.
Good Day.
